One experiment of spacing between rows with different heights of the foliar hedge were started in 1986 in Pully (Switzerland) using Chasselas vines on the experimental estate of the Agroscope Changins-Wädenswil Research Station ACW. At the same shoot load and the same clusters number per vine, the increasing of the row spacing led to an increase of the yield per plant but to a strong decrease of the yield per square meter, without improvement of the sugar content in the must. The same observation was made for the total cane weight. The ratio of exposed leaf surface per kg of grapes (SFE/kg) was a valuable tool in explaining sugar content in musts. The row spacing had only little effect on must acidity, berry weight and bud fertility. With increasing vine spacing the number of roots per vine increased, but the root density per linear meter diminished.
